"SaaS" stands for Software as a Service in the context of cloud services. It refers to a software distribution model in which applications are hosted on a cloud infrastructure and made available to users via the internet. Instead of installing software locally, users can access it through a web browser, which facilitates easy updates and maintenance. SaaS models typically operate on subscription-based pricing, allowing organizations to scale their usage based on needs. Common examples include Google Workspace and Salesforce.
